Before you get into all the calculations, answer this question: what do you want the bullet to do when it hits what you're shooting at? AccuBond at 2600 fps. These days, most bullet data is published with BC numbers for the traditional G1 drag model, but given the explosion of long-range shooting interest, more are also publishing numbers for the G7 model which is more accurate for sleek and slender long range bullets. Mathematically, it is the ratio of a bullet's sectional density to its coefficient of form. Personalize your experience. I dont see how a BC can be constant for varible velocities over a given trajectory. Simply, the faster one starts out, the more remaining velocity it will have at the target. . There are just so many factors to consider, many of which the manufacturer cant know, including atmospheric conditions, the drag created by your rifling, and more. Let's compare the practical ballistics of a traditional flatbase bullet with a modern high-ballistic coefficient bullet when both are zeroed at 200 yards and fired in standard sea-level conditions. His latest projects include an online course to help people get an FFL (. A high BC bullet can maintain velocity better than a low BC bullet under the same conditions. Be careful here. How much a bullet slows down depends on the density (thickness) of the air and the efficiency of the bullet. The Remington Model Seven is ready, willing and able to handle just about any task. The bigger the ballistic coefficient number, the more slippery the bullet, so it flies farther and faster than one with a lower coefficient.
